Migrating Group Calendar from Oracle Calendar to Exchange

An interesting case came up the past few days as a site was migrating from Oracle Calendar Server to Live@ Edu. 

They maintained a calendar in Oracle for users to post when they were In or Out and wanted to take this to hosted Exchange as a Shared Calendar.

Since the Designate model in OCS is very different from the Delegate model in Exchange, when you're converting the OCS export files, choose this option for the raw data from those calendars and then run an insertion.  You'll get the results you desire.

Why this option? When events were added to the calendar by Designates in OCS they were OWNED by the Designates, and not the actual calendar.  The above option normalizes that for an Exchange environment by making the events owned by the shared calendar.
